Losing 4G sign and cannot connect to Internet and send pics

Does anyone know why this is happening? I can't go on the Internet and send pictures. I tried restarting the phone and taking the battery out and all. I tried messing with the mobile network settings still didn't fix it

Mine does the same thing, but I use wifi when at home so I have not noticed. Maybe it is a network issue on their end. When i turn off wifi I get my 4G/LTE symbol on the top bar so it is working. I still get the same issue as you have pictured. I don't believe that is actually used by AT&T now. In either case even though it says failed mine still works so your issue lies elsewhere if it is not working.
